When a girl is blowing a guy with a big cock, and the guy pulls away and swings his prized manhood back and forth while whipping his chick across her head with his big erect cock...like a caveman does to his woman when he hits her across her head with his big club.

To caveman a bitch is to club her with your huge cock.

I pulled a caveman on my bitch last night with my big cock.

The chick saw stars all night long after I did the caveman on her.

Wayne's big cock left Amanda dazzled after he worked his caveman magic on her.

Most people think that cavemen were simple and stupid creatures but its actually the opposite.
The first cavemen and women had to figure out that a man can stick his penis into a womans vagina a practice now known as sex the most common practice in the world. And they figured out that when a lady got really fat and started feeling something inside her that that thing(a baby had to come out and they were able to do it very succsesfully obviuosly)They also had to figure out that if you don't eat or drink something for a long time then you die!

guy 1:It's so easy a CAVEMEN could do it
guy 2:Whats that supposed to mean
